Hi community,

I am currently facing some serious issues with my AutoCad 2021 on my Macbook Pro 16" (M1 Max, 32GB Ram, 2TB) using Windows 11 on Parallels 18.

When I open a .dwg in our company network and save it, saving takes several minutes and no matter how big the file was, after I save it, it is only a few hundred kb in size. When I or one of my collegues try to open one of my saved files AutoCad says "file not valid". When I save a .dwg on my local machine, everything works fine. When I copy that local file to our network, the "file not valid" error occurs again although the size of the file is the original size.

Has anyone ever experienced this issue and knows how to solve it? My concern is that the ARM-emulation on Windows 11 somehow messes the files up. I already tried severeal settings, but none helped.
